Casey Brown co-authors National Climate Assessment

Dr. Casey Brown, leader of the Hydrosystems Research Group, recently co-authored the water chapter of the latest National Climate Assessment, a comprehensive government report that warms how climate change threatens United States water security. Dr. Brown was one of 300 scientists who authored the report, meant to inform US leaders about how climate change affects land, water, and air across the country.

Physical changes will dramatically reshape human life and the systems that support it. The report also underscores troubling knowledge gaps about how the projected increase in extreme storms and heat will affect the nation’s water supply. “We don’t have a very good grasp as a nation what our water-related risks are,” Casey Brown told Circle of Blue. “We seem to keep learning this every time there’s a flood or drought.”

The water chapter emphasized three elements of human built infrastructure which will be impacted by climate change:
1) water quality and availability will shift
2) dams, levees, drainage systems, and other components of the nation’s infrastructure are aging and poorly designed for increased variability due to climate change
3) water managers will need to prepare for a broader set of climate stresses in the future.
